Disord of visual cortex in neoplasm, right side of brain

This diagnosis code indicates a visual disturbance resulting from damage to the visual cortex, specifically on the right side of the brain, where the underlying cause is a neoplasm. This damage impairs the brain's ability to process visual information received from the eyes.

Use this code when documentation clearly links a patient's visual field defect, visual agnosia, or other cortical visual impairment to a neoplastic lesion affecting the right occipital lobe or other right-sided visual processing centers. Supporting documentation should include imaging reports (e.g., MRI, CT) confirming the presence and location of the neoplasm, along with neurological or ophthalmological evaluations detailing the visual deficits.

• Always sequence the neoplasm code (from categories C00-D49) as the primary diagnosis, followed by this code to indicate the manifestation.
• Ensure the documentation specifies "right side of brain" and explicitly links the visual disturbance to the neoplasm.
• Distinguish from visual field defects due to optic nerve or chiasm involvement, which would use different H-codes.
